THREAD-BOARD FOR SPINNING, TWISTING, AND LIKE MACHINES.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed December 20, 1912. Serial No. 737,769.

To all whom, it may concern:

Be it known that I ALBERT H. MoR'roN, a citizen of the United States, residing at l iowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Thread-Boards for Spinning, Twisting, and the like Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make and use the same.

The present invention relates to an improvement in thread boards for spinning, twisting and the like machines.

The object of the invention is to reorganize and improve the construction of thread boards, and to this end the invention consists of the thread board hereinafter described and particularly defined in the claims.

In the accompanying drawings, illustrating the preferred form of the invention, Figure 'l is a plan of the thread board; Fig. 2 is a. side elevation; Fig. 3 is a bottom plan; Fig. 4; is a sectional elevation and Fig. 5 is a section taken on the line 55 Fig. 3.

The thread board 1 has at its outer end the thread guide or finger 2 and is supported at its inner end by the thread board support 3 which is adapted to be bolted to the depending flange of the clotting rail. The thread board 1 consists of a casting having a smooth upper surface stiffened by flanges 4 at its side and front edges. At the rear of the thread board 1 are two cars 5 which receive the hinged pintle by which means the thread board is pivotally supported from the thread board support. The thread guide 2 is supported from the thread board in rigid position with relation thereto so as to be incapable of being turned or otherwise disturbed in its adjusted position except as the result of deliberate intention. The shank 7 of the thread guide is round except at its extreme rear end, as will presently be described, and is received in two holes in lugs depending from the thread board. The front support for the thread guide is afforded by a lug formed by widening the front flange 4 so as to afford provision for a round shank receiving hole therein. The second hole is formed in the lug 8 located near the center of the under side of the thread board casting. This lug also has a round hole in it to receive the end of the thread guide shank 7. The thread guide shank is held from lateral and vertical movement by being supported in these holes in the lugs of the thread board casting. Provision for preventing any rotational movement of the thread guide is afforded by slabbing the sides of the shank 7 as shown in Fig. 5 at the rear end of the shank. The thread guide holder 9 is a thin piece of metal provided with an opening shaped to receive the slabbed end of the shank 7 and provided with feet 10 which engage the under side of the thread board; the thread guide shank is thereby held from rotational movement. Nuts 11 and 12 serve to adjust the thread guide out and in and to secure it in adjusted position. The thread guide is assembled with the thread board by inserting the end of its shank through the hole in the front flange of the thread board and screwing it into the nut 11, then the end of the shank 7 is thrust through the hole in the lug 8, the thread guide holder 9 is slipped over the end of the shank of the thread guide and the nut 12 is screwed on the shank; then the nuts are adjusted to bring the thread guide to the correct position and are tightened to hold it securely in place.

Heretofore it has been proposed to hold the thread guides from turning in the thread board by having the shanks of the thread guides slabbed and received in correspond ingly shaped openings in the thread board, but such openings are difficult to make, ordinarily being required to be made by the process of broaching, to which cast iron does not, in such thin flanges as those with which the thread board is provided, conveniently adapt itself, because such thin pieces of cast iron are liable to be cracked or broken in the broaching operation. In the present construction, however, inasmuch as the holes in the thread board are round, they are con venient-ly drilled and the thread guide is securely held from turning in the finger board by providing it with the thread guide holder adapted to engage the under side of the thread board and by reason of its opening corresponding in form to the slabbed shape of the end of the thread guide shank, hold the latter from turning.

The durability of the cast metal thread board commends its use as it is stifier than sheet metal thread board and is not liable to the deterioration of wooden thread boards.

It is accurate in positioning itself, and clean, having no portions affording spaces for collecting dirt or dust or to catch the cleaning brush. The thread guide is rigidly held in accurate position, and, while having provision tor facility ofadjustinent, is free from meddling interference of the operative.

The invention, viewed in its broader-aspects, is not limited to the illustrated embodiment.

Having thus described the invention, what is claimed is 1. A spinning frame having, in combination, a thread board having two depending lugs provided with round holes, and a thread guide having a shank supported in the holes in the lugs of the thread board, a thread guide holder for holding the thread guide from rotation and nuts to hold the thread guide in adjusted position on the thread board, substantially as described.

2. A spinning frame having, in combination, a cast metal thread board having two depending lugs, a thread guide having a threaded shank provided with a slabbed end supported in the hole in the lugs of the thread board, a thread guide holder having an opening corresponding in shape to the slabbed end of the thread guide shank and nuts to hold the parts in position, substantially as described.

3. A spinning frame having, in combination, a cast metal thread board having a depending lug provided with a hole, a thread guide having a threaded shank provided with a slabbed end supported in the hole of the lug, a thread guide holder having a hole therein corresponding in shape to the slabbed end of the thread guide shank, and nuts on the thread guide located on opposite sides of the lug for holding the thread guide in adjusted position, substantially as described.
